With the purchase of Alltel's licenses and retail stores come 585,000 customers. Alltel's signal rises above 4.6 million people residing in Georgia, Idaho, Illinois, North Carolina, Ohio and South Carolina.
The FCC's concern is that AT&T doesn't have a game plan in place to transition Alltel's more than 180,000 pre-paid customers over to AT&T. It seems that while the FCC is happy with the way that post-paid customers will be making the switch to AT&T, the agency is worried about AT&T's apparent lack of attention to Alltel's pre-paid accounts. And the FCC is worried enough to stop the 180 day review countdown on day 175. AT&T says it will continue to work with the FCC to settle all issues.
